' Application filed April 12, 1 926."-Se ria1 no.1 101,593;

This invention relates to form locating forms on a platen;

The object of the invention is to facilitate the rapid manipulation or locat on 01' forms ,by means of a sinuous locating edgev extended alongthe form and coactingwith alocator over which the sinuous edge oi the form 1 will move freely as the form is shifted to selected'locations.

Another object of the invention is toprovide forms having marginal locating. means coacting with a locator which will arrest or tend to arrest the form in successive loca tions and which Will pe mit the' form to move in a single direction in contact withxa guide when seeking the "desired position as, for instance, a part1cular hne' location;

' Another object of the invention is'to provide a form having marginal locating means designed to-h ave rolling contact with a' locator. t

A still further object of the'invention is to provide a disappearing locator coacting with the marginal locating edge of a; form but'yieldable' in onedirection as the form is moved-in another direction to selected loca- I Figure 7 is a sectional tionsp' g A still further object is to provide aform locato'r adapted to coact with the marginal locatingedge of'a form and arranged to be retained in'anlnactive position when its use isnot desired.

In the accompanying drawings: Figure 1 is airagmentary view'of the platen of an 'Elliott Fisher billing'machine equipped in accordance with my invention, the form being indicated as riding over the locator.

For the purp'oseofthisdisclosure, tliein-i vention is shown inconnection with. theilat platen ,1 0f. the Elliott-Fisherbookkeeping machine of co1nmerce.=,'lhis platen is'usually mounted in a frame 2 from aside rail. of which extends over, the platen, a form or paper clamp 3 against which the form 4: is held by the platen which'is depressible from the writing plane to facilitate"th'e insertion,

It is my purpose to improve or make easier the locating v operation and alsoto renderthe locating margin of'the fo rniless liable :tojmutilation,

by imparting to the edge of the form a' sinuous contour made up of reversely curved contours resulting in a series of identical compound curves and also defining-alternate projections 7 and depressions 8 of identical dimensions and contoun This configur'a tion islnot only of such unlformly 8111110118" character as to facilitate 1ts movement over the locator 9, butitrwill be noted'that the lugs or projections 17 are formed with wide bases and are wholly without corners-so that the tendency of these projections to bend a or break is reduced to the minimum; The

the form on the platen is accomplished when the platen is in its depressed position. The

locating edge of the form is moved against the side rail of the platen frame which constiftutes an alignment guide and is then moved backward or forward to the proper line location with the sinuous edge of the form moving freely over the curved face of the locator until the selected location is reached. When this is accomplished, the locator will be fitted snugly within a recess of the form and the locating edge of the latter will be in aligning engagement with the aligning guide 2. While this movement of the form in contact with the locator is comparatively free, its freedom of movement may be increased by utilizing a rotary locator 9 (see Figs. 5 and 6) in the form of a roller mounted in a bearing 11 secured to a shank 10 Obviously the movement of the form past the locator necessitates relative lateral movementof these elements and while the form is the element so moved when the locator is in fixed position as in the first six views of the drawings, it is contemplated to so mount the locator that it may have a fixed location in use orout of use, or yieldingly located so as to yield laterally as the form is moved along the alignment guide in constant contact therewith. For instance: in Figure 7 the locating roll 9 is mounted in -a swinging bearing 12 pivoted at 13 within a recess Between the bearing and the'bottom of a recess in the guide is mounted a spring 15 encircling a' bolt 16 extended outwardly from the bearing 12 and threaded at its outer end to receive a nut 17 by means of which the locator may be adjusted or drawn back into the recess 14 when the use of the locator is not desired. In Figure 7 the locator 9 is shown in its active position, and it will be obvious that if this roller is engaged by the sinuous 10- eating edge of a form, it will recede or disappear repeatedly within the recess against the resistance of the spring 16 as the form is moved along against the alignment guide.

In Figure 7 is also shown a stop screw 18 which may be advanced into contact with the bearing 12 to prevent inward movement of the locator, if it is desired to'maintain the latter in fixedlocation. In this event the movement of the form along the guide will necessarily be accompanied by lateral movement of the form instead of lateral movement of the locator;

As regards the term edge employed, par ticularly in the appended claims, it is to be understood as applying to the edge wall of the sheet as distinguished from the marginal surface.

What I claim is:

1. In combination, a flat platen, a locator disposed at one edge of the platen and having a convexly curved semi-circular face, and a work sheet movable on the platen past the locator to difierent line positions by pressure exerted on the sheet and having a locator engaging edge formed of alternately reversed curves of the same are of a circle providing equi-distantly spaced arcuate indentations for receiving said face of the 10- cator to determine line positions of the sheet and a line of intermediate arcuate cams movable on the locator when pressure is exerted on the sheet in thelongitudinal direction of the line of indentations and cams.

2. In combination, a flat platen, a work sheet movable thereover to different line positions by pressure exerted on the sheet in a line spacing direction and having a series of locating cams and intermediate notches along one side edge thereof, a guide for engaging'said edge of the sheet to square the sheet on the platen, a locator for engaging said notches to locate the sheet in different line positions and yieldingly mounted to be retracted by said cams when suchpressure is exerted on the sheet whereby the sheet may be moved to different-line positions with its edge constantly engaging said guide, and means for locking the locator in retracted position whereby a work sheet having a straight edge may be used in conjunction with said guide.

In testimony whereof I have affixed my signature.
